How do I solve this problem?

Liono4ka [1.6K]

Answer:

$10100$

Step-by-step explanation:

Use this formula,

$\frac{n}{2} (2 {a} + d(n - 1)$

where n is the amount of even intergers, a is the starting term, d is the common difference.

the amount of even intergers from 2 to 200 is 100
The starting number is 2
The common difference is 2

$\frac{100}{2} (4 + 2(99)$

$50(4 + 198)$

$50(202)$

$10100$
